Re: ask for help : gr-osmosdr build failed

Hi, it seems you've triggered an issue recently introduced via gnuradio master: http://gnuradio.org/cgit/gnuradio.git/commit/?id=9297c84dfdae3002677f759ef2… Their config.h basically overrides our build-time generated one which not only effectively disables every single source functionality but also causes the build error you experienced. I've just pushed a small workaround for that, please test it & report. One second issue i've noticed is that in your configuration every single option seems to be enabled, although not all dependencies have been detected. Usually a full configuration should look like in the attached file. Best regards, Dimitri I failed when I " make ". the make error is : /tmp/gr-osmosdr/lib/osmosdr_source_c_impl.cc: In constructor ‘osmosdr_source_c_impl::osmosdr_source_c_impl(const string&)’: /tmp/gr-osmosdr/lib/osmosdr_source_c_impl.cc:117:16: error: ‘GR_OSMOSDR_VERSION’ was not declared in this scope /tmp/gr-osmosdr/lib/osmosdr_source_c_impl.cc:117:47: error: ‘GR_OSMOSDR_LIBVER’ was not declared in this scope make[2]: *** [lib/CMakeFiles/gnuradio-osmosdr.dir/osmosdr_source_c_impl.cc.o] Error 1 make[1]: *** [lib/CMakeFiles/gnuradio-osmosdr.dir/all] Error 2 make: *** [all] Error 2 the cmake output is : -- Build type not specified: defaulting to release. -- Extracting version information from git describe... -- Configuring Boost C++ Libraries... -- checking for module 'gnuradio-iqbalance' -- package 'gnuradio-iqbalance' not found -- Found gnuradio-uhd: /usr/local/include, /usr/local/lib/libgnuradio-uhd.so -- Found gnuradio-fcd: /usr/local/include, /usr/local/lib/libgnuradio-fcd.so -- Will build with gnuradio iqbalance support. -- -- The build system will automatically enable all components. -- Use -DENABLE_DEFAULT=OFF to disable components by default. -- -- Configuring sysmocom OsmoSDR support... -- Dependency LIBOSMOSDR_FOUND = TRUE -- Enabling sysmocom OsmoSDR support. -- Override with -DENABLE_OSMOSDR=ON/OFF -- -- Configuring FunCube Dongle support... -- Dependency GNURADIO_FCD_FOUND = TRUE -- Enabling FunCube Dongle support. -- Override with -DENABLE_FCD=ON/OFF -- -- Configuring IQ File Source support... -- Dependency GNURADIO_CORE_FOUND = TRUE -- Enabling IQ File Source support. -- Override with -DENABLE_FILE=ON/OFF -- -- Configuring Osmocom RTLSDR support... -- Dependency LIBRTLSDR_FOUND = TRUE -- Enabling Osmocom RTLSDR support. -- Override with -DENABLE_RTL=ON/OFF -- -- Configuring RTLSDR TCP Client support... -- Dependency GNURADIO_CORE_FOUND = TRUE -- Enabling RTLSDR TCP Client support. -- Override with -DENABLE_RTL_TCP=ON/OFF -- -- Configuring Ettus UHD support... -- Dependency UHD_FOUND = TRUE -- Dependency GNURADIO_UHD_FOUND = TRUE -- Enabling Ettus UHD support. -- Override with -DENABLE_UHD=ON/OFF -- -- Configuring Osmocom MiriSDR support... -- Dependency LIBMIRISDR_FOUND = TRUE -- Enabling Osmocom MiriSDR support. -- Override with -DENABLE_MIRI=ON/OFF -- -- ###################################################### -- # gr-osmosdr enabled components -- ###################################################### -- * sysmocom OsmoSDR -- * FunCube Dongle -- * IQ File Source -- * Osmocom RTLSDR -- * RTLSDR TCP Client -- * Ettus UHD -- * Osmocom MiriSDR -- -- ###################################################### -- # gr-osmosdr disabled components -- ###################################################### -- -- Building for version: 1eb3af22 / 0.0.1git -- Using install prefix: /usr/local -- Configuring done -- Generating done -- Build files have been written to: /tmp/gr-osmosdr/build * *

rtl-sdr, SDRSharp under Ubuntu/mono, high CPU load - compared with GQRX
by Lorenz Wiedemann 10 Mar '13

10 Mar '13

Hello, I am running an RTL2832 USB stick (R820T tuner in it) and SDRSharp via Mono under Ubuntu 12.04 with a Pentium-M 1.5GHz and 1,5 GB RAM. SDRSharp With sample rates of 0.25M and 1.024M, I'm "suffering" from 100% CPU load and temperatures around 70°C - this can't be healthy for the laptop... Switching the waterfall off and speed etc. to minimum doesn't help very much. RDS is displayed fine, all functions seem to be OK. RAM space is not filled up (30%). Any advice for a "smoother" running on such an "old" machine...? http://superkuh.com/rtlsdr.html#sdrsharpappnote said "it can even run on my old 1.8Ghz P4 laptop". GQRX GQRX did run using the QtPro way as described in the wiki, but after recent update of GQRX the DC spike at centre frequency appeared (it wasn't there before), and massive stuttering of audio and the "OOOOOO"s in terminal window at a lot of different sample rates made the usage of GQRX worse. (right, this should be posted in a GQRX forum...) Anyway, did someone notice that GQRX update (ca. first days of march 2013) lead to problems ? thanks, Lorenz

dump1090 - forked repo and added mysql support - some artwork
by Oliver Goldenstein 09 Mar '13

09 Mar '13

HI All ! Many thanks Salvatore for that very impressive piece of software. I extended dump1090 to make use of a mysql database: http://dl6kbg.blogspot.de/2013/03/dump1090-with-mysql-support.html I will work on the code the next days to improve it for a more easy db setup. Some results and a description you may see here: http://dl6kbg.blogspot.de/2013/03/dump1090-with-mysql-support.html the forked repo is here: https://github.com/dl6kbg/dump1090 You need a mysql database called "dump1090" with a table "tracks". You may easily setup the db using the supplied script "tracks.sql" Username and password ist coded for now as mysql user: root mysql password: root. Run: ./dump1090 --mysql Have fun ! 73 Oliver DL6KBG

the next level in Software Definition
by Jay Salsburg 08 Mar '13

Gird you Grid for the next level in Software Definition. We are now stuck in Software Defined Radio (SDR). Next is Software Defined Instrumentation (SDI) with intriguing choices like the Vector Signal Transceiver (VST) for Device Testing.

Dear developers! I would like to ask the driver for the R820T osdmocom rtlsdr tuner use of this IFGAIN conrtol was, and if his shirt, the GNU Radio source how to use it (I think python command) I'm a hardwer working towards, and it would be important that we have a value ifgain radio) thank you Jakab Szilárd HUNGARY HA1003SWL

New item for the "Known Apps" section of OSMOCOM rtl-sdr
by Thomas Frisch 03 Mar '13

03 Mar '13

Hello osmocom-sdr-Team, i spent some time to get familiar with GNU-Radio and RTL-SDR stuff and have implemented an decoder for the FS20 wireless home automation protocol. Maybe this is something for the "Known Apps" section in the OSMOCOM rtl-sdr wiki. Since i am a hardware/FPGA/RF guy, my programming skills are not the best, not at all in python, so i hope the code is not too scary. Name: rtl_sdr_FS20_decoder Type: gnuradio app Author: Thomas Frisch URL: https://github.com/eT0M/rtl_sdr_FS20_decoder.git My compliments to the whole OSMOCOM Team, you are doing a great job. regards Thomas
